Hybrid tea rose plant named ‘WEKrigoyelo’

ABSTRACT

A new variety of Hybrid Tea rose suitable for garden decoration, having flowers of vibrant pink with a golden glow coloration.

Classification: The present invention relates to a new Rosa hybridaplant.

Variety denomination: The new plant has the varietal denomination‘WEKrigoyelo’.

BACKGROUND OF THE INVENTION

This invention relates to a new and distinct variety of Hybrid Tea Rose.It has as its seed parent the variety known as ‘DORviso’ (not patented)and has an undisseminated seedling of my creation as its pollen parentwith the following genetic origin Seedling×‘O Sole Mio’.

SUMMARY OF THE INVENTION

Among the features which distinguish the new variety from otherpresently available and commercial rose cultivars known to the inventorare the following combination of characteristics: its peduncle bearinglong prickle-like stipitate glands, its bud surface bearing few longfoliaceous appendages, many stipitate glands and hairs and its evenvibrant pink with a golden glow flower coloration that lasts throughoutthe life of the flower. The plant has an upright somewhat spreadinggrowing habit, suitable for outdoor garden decoration.

Asexual reproduction of the new variety by budding as performed in KernCounty and Upland, Calif., shows that the foregoing and otherdistinguishing characteristics come true to form and are established andtransmitted through succeeding asexual propagations. ‘WEKrigoyelo’ maybe asexually propagated by budding and grafting. The budding andgrafting successfully occurred on the plant/rootstock Rosa hybrida cv.‘Dr. Huey’ (unpatented).

COMPARISON WITH PARENTS

The new rose may be distinguished from its seed parent, ‘DORviso’ by thefollowing combination of characteristics: whereas ‘WEKrigoyelo’ bearsflowers of vibrant pink with a golden glow coloration, ‘DORviso’ bearsflowers of deep pink coloration. The new variety has an upright somewhatspreading medium height growing habit (about 115 to about 140 cm. inheight), whereas the seed parent has an upright moderately compactsignificantly shorter growing habit. ‘WEKrigoyelo’ bears young leaves ofpale green coloration, whereas ‘DORviso’ bears young leaves ofsignificantly darker olive green coloration.

The new variety may be distinguished from its pollen parent, anundisseminated seedling of my creation by the following combination ofcharacteristics: whereas ‘WEKrigoyelo’ bears large sized flowers (about8.2 to about 14.7 cm. in diameter) of vibrant pink with a golden glowcoloration, the undisseminated seedling bears significantly smallerflowers (about 5.9 to about 8.4 cm. in diameter) of medium yellowcoloration. The new variety is classified as a hybrid tea rose with anupright somewhat spreading medium height growing habit (about 115 toabout 140 cm. in height), whereas the pollen parent is classified as afloribunda rose with a rounded and compact significantly shorter growinghabit.

COMPARISON WITH THE CLOSEST COMMERCIALLY AVAILABLE CULTIVAR

The closest commercially available cultivar to the new variety is theseed parent ‘DORVISO’.

BRIEF DESCRIPTION OF ILLUSTRATION

The accompanying photograph illustrates the new variety and shows theflowering thereof from bud to full bloom depicted in color as nearlycorrect as it is possible to make in a color illustration of thecharacter. Throughout this specification, color references and/or valuesare based upon the Colour Chart of The Royal Horticultural Society(1966) except where common terms of color definition are employed.

DESCRIPTION OF THE NEW VARIETY

The following description is of 3 to 4 year-old rose plants of the newvariety grown outdoors in Upland, Calif. in the month of September.Phenotypic expression may vary with environmental, cultural and climaticconditions, as well as differences in conditions of light and soil.

FLOWER

The new variety usually bears its flowers singly. Flowers are borne onstrong short to medium length stems (about 15 to about 65 cm.).Outdoors, the plant blooms abundantly and nearly continuously during thegrowing season. The flowers have a slight tea fragrance.

BUD

The peduncle is about 2.3 to about 5.6 cm. in length, of somewhat heavycaliper (about 0.3 to about 0.5 cm. in diameter), and usually erect tomoderately stiff. It is rough with many long prickle-like stipitateglands, few hairs and some small prickles. Peduncle color is between144A and 143A.

Before the calyx breaks, the bud is about 1.1 to about 2.0 cm. indiameter at the widest point, about 1.8 to about 2.7 cm. in length, andpointed in shape. The surface of the bud bears few long foliaceousappendages, many stipitate glands and hairs usually with slender muchcut foliaceous parts extending beyond the tip of the bud about ¼ or moreof its length. Bud color is between 144A and 143A.

The sepals are about 2.8 to about 4.1 cm. in length and about 0.7 toabout 1.3 cm. in width at the widest point. The outer surface color ofthe sepal is between 144A and 143A. The inner surface color of the sepalis between 137A and 138A and covered with fine wooly tomentum; sepalmargins are lined with many stipitate glands and few hairs.

The receptacle of the flower is of very short length (about 0.2 to about0.4 cm.) and thin in caliper (about 0.4 to about 0.7 cm. in diameter).The receptacle is usually nearly flat to sometime somewhat rounded inform. Its surface is moderately smooth with few hairs and stipitatesglands and with thin fleshy walls. The receptacle color is between 144Aand 143A.

As the petals open (after the calyx breaks), the bud is about 2.5 toabout 3.4 cm. in diameter at the widest point, about 2.8 to about 3.8cm. in length, and moderately ovoid to somewhat pointed in form. Thecolor of the under and upper surfaces of the newly opened petals isbetween 53B and 47B. At the point where the petal attaches on the undersurface of the newly opened petals, there is a moderately small zone ofbetween 3C and 4B. At the point where the petal attaches on the uppersurface of the newly opened petals, there is a large zone of between 4Aand 5C.

BLOOM

When fully open, the bloom ranges from about 8.2 to about 14.7 cm. indiameter. Petalage is double with about 23 to 30 petals and about 1 to 5petaloids irregularly arranged. When partially open, the bloom form ishigh centered to somewhat cupped, and the petals are moderately tightlyspiraled to cupped with petal edges slightly reflexed outward. Whenfully open, the bloom form is cupped and the petals are loosely cuppedto somewhat undulated with petal edges moderately reflexed outward.

PETALS

The substance of the petals is moderately heavy and of medium tosomewhat thick thickness, with upper surfaces moderately satiny andunder surfaces slightly shiny to matte. The petals are about 3.7 toabout 5.9 cm. in length and about 3.3 to about 6.7 cm. in width at thewidest point. Petal margins are entire.

The outer petals are nearly round in shape with rounded apices.

The inner petals are broadly obovate in shape with rounded apices.

Petaloids are about 1.4 to about 3.4 cm. in length and about 0.9 toabout 1.8 cm. in width at the widest point. Petaloids are irregularlyshaped sometimes nearly rounded and sometimes somewhat oblanceolate withrounded apices.

NEWLY OPENED FLOWER

The under and upper surface color of the outer petals is between 63B and58C. At the point where the petal attaches on the under surface there isa moderately small zone of between 5C and 6C. At the point where thepetal attaches on the upper surface there is a large zone of between 6Cand 7C.

The under and upper surface color of the intermediate and inner petalsis between 58B and 51A.

The under and upper surface color of the petaloids are similar incoloration to the upper and under surfaces of the intermediate and innerpetals.

The general tonality of the newly opened flower is between 58B and 51A.

THREE-DAY-OLD FLOWER

The under and upper surface color of the outer petals is between 63B and61D sometimes fading to between 68C and 62B on the outer edge of theouter most petals. At the point where the petal attaches on the undersurface there is a moderately small zone of between 5C and 6C. At thepoint where the petal attaches on the upper surface there is a largezone of between 6C and 7C.

The under and upper surface color of the intermediate and inner petalsis between 63B and 61D.

The under and upper surface color of the petaloids are similar incoloration to the upper and under surfaces of the intermediate and innerpetals.

The general tonality of the three-day-old flower is between 63B and 61D.

On the spent bloom, the petals usually drop off cleanly.

In September in Upland, Calif., blooms on the bush growing outdoorsgenerally last about four to five days. Cut roses from plants grownoutdoors and kept at normal indoor living temperatures generally lastabout four to five days.
